IMPROVEMENT IN ANVILS.

Specification forming part of Letters Patent No. 218,343, dated August5, 1879; application led April 25, 1879.

To all whom 'it may concern:

Be it known that I, HERBERT WADswoRTH, of Geneseo, Livingston county,New York State, have invented certain new and useful Improvements inAnvils or devices for blocks over which to beat malleable substances,such as iron, steel, copper, and the like, of which the following is aspecification.

It is my object to enable blows to be given by a steam or power hammeron and around an anvil, much as a smith strikes with a handhammer themetal, sometimes on aflat surface,

sometimes over an angle, sometimes over a curve, and sometimes,whendesirous of bending a bar, far away from the supporting-block.

To effect this result I combine and arrange the block or anvil and thesteam or power hammer in such manner that difterentportions of theanvil, as desired, may be brought under and in the line of stroke of thehammer. I prefer for the purpose to make the anvil movable in ahorizontal plane under the hammerthat is to say, in a plane at rightangles with the line of movement of the hammer; and the best way, on thewhole, to thus make the anvil movable is to mount it on a carriageadapted to revolve on a vertical pivot or axis which is eccentric to thelongitudinal axis of the hammer.

The nature of my invention, and the manner in which the same is or maybe carried into effect, will be understood by reference to theaccompanying drawings, in Which- Figure 1 is a perspective view of amovable anvil arranged in accordance with my invention under asteam-hammer. Fig. 2 is an elevation of the same, partly in section, inorder to show the pivoting of the anvil-carriage. Fig. 3 is aperspective view of the anvil. 4 is a plan of the same. Fig. 5 is aperspective view of a modified form of anvil.

In Figs. l and 2 I have shown combined a vertically-movin g steam orpower hammer, A, and an anvil, B, movable in a plane at right angles tothe path of movement of the hammer, with a view to varying the relativeposition of the two parts. For this purpose the anvil B, which may be ofthe form shown, or of any other suitable form, is eccentrically ixedupon a horizontal rotary platform or turn-table, C, whose pivot a oraxis of movement is eccentric with respect to the hammerthat is to say,is to one side of the hammer.

The steam-hammer mechanism may be of any approved kind, and requires nodescription here. That which I have shown in the drawings is intended tobe used in connection with the controllin g-valve apparatus described inmy Letters Patent No. 203,224., dated April 30, 1878, and with theuniversal-jointed lever apparatus described in my Letters Patent No.213,079, dated March 11, 1879.

The lever or handle referred to is shown at b in Fig. 2, and may be usedto connect with and control the power mechanism which moves the anvil oranvil-platform C. This platform, it is manifest, can be moved by anysuitable mechanismfor instance, connecting with the platform by means ofa belt or chain, c, passing around the periphery thereof.

'Ihe anvil is shown separately in Figs. 3 and 4. The dotted circle ineach shows the line in which the blows of the hammer A will fall whenthe table is revolved. Under this arrangement it is manifest the blowsof the hammer will fall at one position of the table on top of theanvil, at another just outside the anvil, at another some distance fromthe anvil, and so on, according as the table is revolved.

Any desired outline or configuration may be given to the anvil,according to the requirements of work-as, for instance, an anvil of theform shown in Fig. 5 maybe used with good results under somecircumstances.

In every case, however, the shape of the block and its position on theplatform will vary with the pattern of power-hammer, and with theconditions of the foundation required and attainable.

I have'described in this specification only so much of the differentstructures represented as needed to illustrate my invention, the mainfeature of which I consider to reside in the provision for adjustment ina plane at about right angles with the line of reciprocation or the axisof the hammer, with a view to varying the relative positions of thehammer and anvil, for the purposes already stated.

I am aware that an anvil or block of cylindrical form has been mountedto revolve on a horizontal axis, with a view to bringing differentportions of its periphery under the hamn adapted to rotate upon avertical axis eooentric to the axis of the hammer.

2. The combination, substantially as hereinbefore set forth, with a.power-hammer, of an anvil-carriage adapted to rotate on a vertical axiseccentric to the axis of the hammer, and an anvil eccentricaily placedon said carriage.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing Witnesses.
